| Summary: | Most of the cost for production of commercial production feeds used in marine penaeid shrimp culture can be attributed tothe provision of dietary protein. Because protein is comprised of amino acid residues, it is surprising that relatively littleresearch has addressed the nutritional requirements of shrimp for essential amino acids. This is especially critical for thecontinuation of efforts to reduce fish meal use in commercial production feeds. Requirement data, in combination withthat for protein and energy digestibility, will allow for the manufacture of more accurate least-cost production feeds forLitopenaeus vannamei and other species. This paper provides historical results of essential amino acid requirementresearch on marine penaeid shrimp, comments on methodological approaches and reports on current preliminary efforts todetermine apparent requirement for methionine by L. vannamei.
